The ionization energies (often called ionization potentials) of neutral and partially ionized atoms are listed in this table. Data were obtained from the compilations cited below, supplemented by results from the recent research literature. Values for the first and second ionization energies come from Reference 6. All values are given in electron volts (eV). Following the traditional spectroscopic notation, columns are headed I, II, III, etc. up to XXX, where I indicates the neutral atom, II the singly ionized atom, III the doubly ionized atom, etc. The first section of the table includes spectra I to VIII of all the elements through rutherfordium; subsequent sections cover higher spectra (ionization stages) for those elements for which data are available.

The hyperfine structure of a rovibrational state of can be described by the following effective spin Hamiltonian [26]: where , , and are the spins of the deuteron, proton, and electron, respectively, and is the total angular momentum excluding electron and nuclear spins (denoted by in standard spectroscopic notation). Here and throughout the paper, spin and angular momentum operators are written in units of ℏ and are thus dimensionless. The coefficients , are then energies and depend on the rovibrational state , where v stands for the vibrational quantum number. This Hamiltonian includes all spin-dependent interactions that appear at the leading order , i.e. appear in the Breit-Pauli Hamiltonian, except for the proton-deuteron spin-spin contact interaction, which is negligibly small because of the strong Coulomb repulsion between the proton and deuteron.
